When I was in college there was a group of students who didn't always practice their faith, but when Ash Wednesday rolled around all decided to band together in giving up a few particular sins common among college students.

A Protestant pastor among my Facebook friends once declared that he didn’t want to hear what anyone else was giving up for Lent. He asked if people had forgotten Matthew 6. That’s the chapter in which Jesus tells people to act as if they weren’t fasting when they were. The pastor clearly felt vexed, and was a little rude about it.
